Each school is awarded a final score based on the performance of each student representing their academic facility.

When analysing the average scores of each student per school there are three possible data formulas available to use: mean, median and mode.

The Rookies uses median. The median is the middle point of a number set, in which half the numbers are above the median and half are below. A median is intrinsically understandable. It is the middle number when the values are put in order.

The most important factor here is that a median is not affected by outliers. This means that schools are not penalised for incomplete entries and schools are not favoured for a single high score that is not the norm. Student scores often have outlier values and using the median is the more robust solution to determine an average.

Important details about how a school score is calculated:

• Schools with < 5 student entries are excluded from ranking.
• Incomplete student entries are removed from calculations. No penalties.
• Each student receives a performance score. Max 100 points. (Student Score)
• Median students score calculated per school. Max 100 points. (Median Student Score)
• Each category finalist receives 10 bonus points toward School Score.
• Each category runner up receives 15 bonus points toward School Score.
• Each category winner receives 20 bonus points toward School Score.
